SHADE-MOUNTING.

SPECIFICATION forming part of Letters Patent No. 763,819, dated June 21,1904.

Application filed July 30,1903. Serial No. 167,554. (No model.)

To all whom it may concern:

Be it known that we, JOHN B. OLSEN and WVILLIAM J. FENNELL, residing atMilwaukee, in the county of Milwaukee and State of Wisconsin, haveinvented a new and useful Improvement in Shade-Mountings, of which thefollowing is a description, reference being had to the accompanyingdrawings, which are a part of this specification.

Our invention is embodied in improved mountings for shades, especiallythat class of flexible cloth shades that are used with windows inresidences and buildings, the object of the invention being chiefly toprovide improved means whereby the shade can be raised and loweredbodily, can be readily wound up on its roller, and will be automaticallyheld in this wound or rolled up condition, but so as to be capable ofbeing readily unwound by merely pulling on a cord therefor withouthaving to release any catch or disengage it from any stop, and otherincidental benefits in construction and operation incidental to saidchief features of the improvement.

The invention consists of the apparatus, its parts and combinations ofparts, as herein described and claimed, or the equivalents thereof.

In the drawings, Figure 1 shows a fragment of a window-casing with ashade mounted thereon by our improved apparatus. Fig. 2 is an enlargeddetail of the construction as seen from the front. Fig. 3 is an enlargedend view of a detail of the construction.

In the drawings, represents a fragment of a window casing or frame.

B is a shade, of cloth or other flexible material. The shade B at oneend is secured along the edge thereof to a roller 2, on which the shadeis adapted to be rolled up in a manner in common use. The roller isprovided with axial spindles 3 3, each provided with disks fixed thereonat a little distance apart,

forming a spool 4, on which the roller-cords 5 5 are adapted to wind,the cords being secured thereto at their ends. These spools are rigid onthe spindles and are located on the outer ends of the spindles at adistance from the ends of the roller, and clutch members 6 6, one oneach spindle, are mounted loose on the spindles, the clutch membersbeing in the form of small plates which fit outwardly against the innerends of the spools, thereby acting as friction-clutches on the spindles.The clutch members are held yieldingly in engagement with the spools byexpansionsprings 7 7, coiled about the spindles and resting at one endagainst the ends of the roller and outwardly against the clutch members.

The roller-cords 5 5, running upwardly from the spools i 4, pass looselythrough guides 8 8 therefor, fixed in the clutch members 6 6 a littleabove the spindles, and thence run over pulleys 9 9 in brackets 10 10,adapted to be afiixed to the window-casing, as shown in Fig. 1. Thebracket 10 is provided with a pulley 9, Fig. 4, having a single groove,as only one of the cords 5, running from the spindle 3, is carried inthis bracket, and over which it runs across the window-opening to thebracket 10, which is provided with a pulley 9', having two groovesadapted to carry the two rollercords 5 5, one from each end of theroller, and keep them separate in position, and from which double pulleythe cords preferably run over a rigid pin 11, which we advisably placein this bracket at a little distance from the double pulley, thuscarrying the cordsa little farther outwardly, from which position theyrun down to a convenient location to be taken hold of by a person formanipulating the shade. A pin or cleat l2, fixed in the casing at aconvenient location, will serve as an anchor or post about which towind, and thereby fasten, the roller-cords releasably.

The brackets 10 10 are advisably made of sheet-steel, being so cuttherefrom as to provide a top member 13 and side members l4 14, the sidemembers being provided with apertures for the axles of the pulleys andthe top member being provided at its outer end with a sharp projectingend 15, adapted to be driven into the side members of the windowcasing,against which the top member 13 of the bracket is placed in putting upthese shade-mountings and to which the bracket is chiefly secured bymeans of a screw through the aperture 16. A shade-cord 17 may beattached to the shade, and the free end of this cord may be tied to thelower edge of the clutch member 6, an aperture therein being providedtherefor to keep the shade-cord from swinging around or getting tangledup with other parts.

In use assume that the shade B is entirely wound up on the roller 2 andthat the roller is by means of the cords 5 5 drawn up close to thebrackets 10 10 and that the cords 5 5 when the shade is in thiscondition and position are not wound on the spools 1 4. The shade may bethen pulled down by drawing on the shade-cord 17, the roller-cords beingunfastened from the cleat 12 to such extent as is desired, thisoperation resulting at the same time in Winding the roller-cords 5 5 onthe spools 4;. If then it is desired to let the entire shade down fromthe top of the window, so as to leave an unobstructed space above theshade, this can be done by again loosening the roller-cords5 5 from thecleat 12, so that the shade may be put in a condition and positioncorresponding with that shown in Fig. 1, in which the shade is let downa distance from the top of the window and is partially unrolled. In thisposition, the clutch members 6 6 being held against revolution by theupwardly-extending and taut cords 5 5, these clutch members will bytheir frictional contact with the spools 1 1 hold the roller againstrotation, so that the shade will not by its weight cause the roller togive way and the shade be unwound therefrom. If now it is desired toroll up the shade, the roller-cords 5 5 can be unfastened from the cleat12, and on pulling down thereon the roller and the shade will be liftedbodily to the brackets 10 10, and then with further pull on therollercords the shade will be wound up by the rotation of the roller,the roller being rotated by the forced unwinding of the roller-cordsthereon against the friction-holding of the clutch members 6 6.

What we claim as our invention is- 1. In combination, a flexible shade,a roller on which the shade rolls up, spindles fixed in the roller andprovided with cord-spools, nonrevoluble friction-clutch members loose onthe spindles, springs holding the clutch members yieldingly to thespindles, supportingcords winding on the spools, and brackets secured toa fixed support and carrying the sup porting-cords.

2. In shade-mountings, a roller, spindles fixed in the roller,cord-carrying brackets secured to a Window-frame, roller-supportingcords winding on the spools and running on the brackets, and meansadapted to hold the roller yieldingly against rotation.

3. In shade-mountings, a roller, spindles fixed in the roller, spools onthe spindles,

clutch members loose on the spindles and bear- \Vitnesses:
